BRIDGING FORJOISTS.

SPECIFICATION forming part of Letters Patent No. 267,385, dated November 14, 1882. Application filed July 27, 1882. (No model.)

To all whom it may concern Be it known that I, HARRY B. WALTER, a citizen of the United States, residing at Oineinnati, in the county of Hamilton and State ofOhio, have invented a certain new and useful Improved Bridging for Joists, of which the following is a specification.

In the construction of large and permanent buildings, whether of brick, stone, wood, or other material, and alsoin any large structures where joists are used, it has been customary to stay the ceiling or floor joists, and sometimes alljoists, with a series of small pieces of wood,-ca1led bridging, placed in aslanted direction between the joists and permanently and securely nailed thereto, the ends of this bridging being first sawed or cut with beveled edges to make a clean fit against thejoists.

The position of bridgingis shown in Figure 2 of the drawings accompanying this application, F being the floor, B the bridging, andJ the joists. This work ofputting in bridging is usually done before the floor is laid. The upper end is nailed to the joist without difficulty.

The lower ends of the bridging cannot, however, be easily reached from above, and it has therefore been customary to resort to scaffolding to nail securely from below.

Fig. 1 shows an improved piece of bridging which I have invented. At one end it is provided with one or more nails, the heads or blunt ends of which are inserted and embed ded in the wood. The said nails are shown in thedrawings in Fig. 1 byA A. Another nail or lug of metal is inserted at O, as shown in said drawings, Fig. 1, in such a position as to cross the ends of the nails, so as to secure them firmlyin position and preventtheheads beingdriven into the wood. This nail at 0 may not be necessary, this depending on the hardness of the wood and the size of the head of the nail.

The best plan of manufacturing this improved bridging is to insert the nails in the bridging by the aid of true and accuratelybored holes; but such method is not necessary if care be used in inserting the nails.

In the drawings, Fig. 1, dotted lines represent lines concealed, and plain lines represent lines in view.

In constructing a building with the improved bridging betweenjoists, the bridging is placed with the sharp points of the nails AA against the face of thejoist. Blows are then administered at the end of the bridging and said nails are driven into the-joist. When same is in place the other end of the bridging can be nailed into place in the ordinary manner. Thusit will be practicable to fasten both ends of this improved bridging without oper-v ating both from the lower as well as the upper side of the joists.

The above plan of inserting the bridging from above is pointedout as the best plan, yet it will readily appear that, should the floor be first laid, it is still practicable to insert the omitted until the ceilings are readyto be plastered the same scaffolding can be used both for nailing bridging and for plastering the ceilings.

What I do claim as my invention, and desire to secure by Letters Patent, is

An improved bridging l'or joists, designed to fit the faces of the joists, provided with nail or nails, the head or heads of'which are inserted within and embedded in the piece of bridging at one end thereof, substantially as described.
